SBI Q4 Miss Hits PSU Banks Hard: NIM in Focus

SBI's Q4 Miss Just Changed the Conversation for PSU Banks [State Bank of India](/stock/SBIN) (NSE: SBIN) dropped 6.6% after Q4FY26 results landed well short of analyst expectations. The headline profit miss was bad enough. But the real damage came from Net Interest Margin compression — the metric that tells you how profitably a bank is actually lending.

Investors sold first and planned to ask questions later. The NIM compression story is the one worth watching closely. When deposit rates stay elevated and lending yields face pressure from competitive pricing — particularly in retail and MSME segments — margins get squeezed from both sides. SBI's scale means it feels these dynamics earlier and more acu...
